Not a toy hauler but I have 2 baths and regret it.
On the surface I like the idea of two bath but unfortunately 2 toilets equates to 2 black tanks...That also means 2 separate discharge pipes.
That means dumping twice or connecting 2 sewer hoses.
It's not the toilet or floorplan I despise it's all the extra dumping and tank maintenance.
Instead of having 1- 1/2 or 3/4 full black tank you end up with 2-1/4 full tanks.
In the end there is more flushing, more connecting more work.
THe additional work is more than the convenience of the 2nd bath is worth. We have no issues with just 1 bath.
If the kids,girls, wife or whomever did the dumping maybe I would tolerate the 2nd tank. But since I'm doing the additional work I despise the additional black tank.
Did I mention there is also a 2nd grey tank!
My 2nd bath is now a closet!
